Specific embodiment
Hereinafter, embodiments of the present invention are described in detail with reference to the accompanying drawings.Below not to the description of embodiment
It should be considered in a limiting sense.The scope of the present invention by embodiments described hereinafter or is not considered as being only illustrative attached
Figure is limited.
Attached drawing is considered as that the element for schematically indicating, and illustrating in attached drawing is not necessarily to scale and shows.Phase
Instead, various elements are expressed so that their function and general purpose will be apparent to those skilled in the art.
It is shown in the accompanying drawings or any company between functions described in this article block, equipment, component or other physics or functional unit
Connecing or coupling can also be realized by being indirectly connected with or coupling.Functional block can be with hardware, firmware, software or combinations thereof come real
It is existing.
Hereinafter, for forbidding UE to the access of network come description technique.Forbid access that can be related to preventing UE and net
The initialization of connection between network.Access is forbidden to can contribute to reduce the overload of the RAN of network.For example, as emergency
Or under the overload situations of congestion, access barred may be beneficial.In general, access barred is realized by the logic in UE.Therefore, energy
Enough reduce the signaling (for example, a part as radio access technology) on Radio Link: this may be since UE is in transmission
Downlink control message is to seek before the access to network to try to be the first to prohibit access.That is, network may be unaware that some UE just
In the access barred of execution, because it is not notified accordingly.
According to some examples, access barred is realized based on each UE.It is connect i.e., it is possible to be individually controlled for each UE
Enter to forbid.Alternately or in addition, various technologies described herein can be used to be grouped into a kind of multiple UE.This has
When referred to as ACB.ACB is a kind of access barred of special shape.ACB is not based on what each UE was realized, but uses UE's
Group/class is realized.
For example, the multiple UE being grouped into same class can correspond to each other for one or more device attributes.Example
Device attribute includes: the communication capacity of UE, narrowband or broadband connections, low time delay service etc.；The device type of UE, it is such as narrow
Band Internet of Things (NB-loT) equipment and machine type communication (MTC) equipment etc.；Network slice associated with UE；The access class of UE
Not, for example, being hard coded into subscriber identity module (SIM)；And the operator of subscriber associated with UE.Access barred can be with
Based on control parameter.Control parameter can be provided from network to UE.Because control parameter is not with UE fixed correlation (for example, hard
It is encoded in the SIM associated with UE of subscriber), it is possible to different control parameters is dynamically assigned to the same UE.
Thus, it is possible to dynamically change the access barred of UE.
This dynamic access forbids that various effects can be promoted.Such as, it may be possible to it is connect with fine granularity level realization
Enter to forbid.If can be assigned control parameters to compared with generally about having ten access categories available with reference to realizing
Multiple UE, to be distinguished between the different ues with higher resolution ratio.Furthermore, it is possible to be flexibly defined by the UE for ACB
Classification.For example, classification can be formed for the device attribute of variety classes and type.It is then possible to customize ACB.One
Example includes joining the conceptual dependency of ACB and network slice (also sometimes referred to as network division).
Various examples described herein can be applied to network slice.It is retouched in 3GPP technology request (TR) 23.799
The example for the concept for being sliced network is stated.Network is sliced the logical partition for generally corresponding to network.In general, being directed to core
Net realizes network slice.Alternately or in addition, network slice can also be realized for RAN.By the way that network to be sliced, transport
Dedicated network function can be provided according to user demand by seeking quotient.For example, some network slice can be optimized to transmit specific clothes
Business.For example, network slice can be used for specific business case.For example, operator can provide low by the way that network to be sliced
Cost web slice, network slice provide limited performance.Can also for certain device attributes (such as device type) come
Realize network slice.For example, loT and/or MTC device can be distributed to one or more dedicated network slices.
In the various examples, bans policy can be considered or distinguish different network slices.For example, can be by depending on
The control parameter limited respectively forbids the access for being sliced associated UE with some network, but is not prohibited by and cuts with another network
The access of the associated other UE of piece.In this way, can be sliced according to network associated with UE to distribute control parameter.
Fig. 1 is instantiated in terms of the framework of network 100.3GPP LTE is realized according to the exemplary network 100 of Fig. 1
Framework.According to 3GPP LTE, Radio Link 101 is defined in RAN 114.Radio Link 101 is limited at evolution node B
(eNB) between the base station of 112 forms and one or more UE 130-1,130-2.Radio Link 101 may be implemented one or
More channels, such as payload channel and/or control channel.
In addition, network 100 includes core net 113.Core net 113 is communicated with RAN 114.Core net 113 includes control layer
And data Layer.Control layer includes control node, such as home subscriber servers (HSS) 115, mobility management entity (MME) 116
And "Policy and Charging Rules Function (PCRF) 119.Data Layer includes gateway node, such as gateway (SGW) 117 and grouping
Data network gateway (PGW) 118.
Between UE 130-1 and the data Layer of core net 113 via RAN 114 and data are established towards access point 121
Connection 160.For example, the connection with internet or another packet data network can be established via access point 121.
The network node 115-119 of core net 113,121 general utility functions and purpose are well known in the present art, because
This, is not required to be described in detail within a context.
Illustration the being given for example only property purpose of network 100 in 3GPP LTE frame.Similar technology can be by easily
Applied to the framework that various 3GPP are specified, such as global system for mobile communications (GSM), Wide band Code Division Multiple Access (WCDMA), general point
Group wireless service (GPRS), GSM evolution enhanced data rates (EDGE), Enhanced General Packet Radio Service (EGPRS), universal mobile telecommunications system
It unites (UMTS) and high-speed packet accesses (HSPA).For example, technology described herein can be applied to 3GPP eNB-loT or
MTC system or the new radio of 3GPP (NR) system.See, for example, 3GPP RP-161321 and RP-161324.Furthermore, it is possible to be easy
Various technologies are applied to the network that various non-3 gpp are specified, such as bluetooth, satellite network, IEEE 802.11x Wi-Fi skill by ground
Art etc..
Fig. 2 is instantiated in terms of the access barred of UE 130.UE 130 seeks to access network 100 via eNB 112.
ENB 112 periodically sends system information block (SIB), for example, SIB 2.In the figure 2 example, it is sent and is connect by UE 130
Receive SIB 5001.UE 130 is not needed in order to receive SIB 5001 and is permanently attached to network 100.
SIB 5001 indicates bans policy.Then, UE 130 is configured as forbidding accessing based on bans policy 5002.
For example, control parameter can be compared with bans policy at 5002.For example, bans policy can define
Ground or impliedly instruction control parameter, which should result in forbid accessing or not should result in, to be forbidden accessing.Bans policy and control
This comparison between parameter may include random contribution.For example, bans policy can indicate that some control parameter causes to forbid
Access or cause the probability for being not prohibited by access.Bans policy can be considered as defining the access barred for available control parameter
Parametrization rule.
For example, starting to carry out UE if judging forbid UE 130 to the access of network 100 in frame 5002
130 with the initialization of the connection of network --- otherwise just abandon connecting trial, 5007.
In this way, in the figure 2 example, the UE 130 in 5007 prohibits access before initializing the connection with network.
When executing 5007, UE 130 may be at off-state or Idle state: here, for example, it may be possible to can not carry out to network 100
Uplink data transmission.It may be without established channel on Radio Link 101.Data connection 160 may not set up.It can keep away
Exempt from random access procedure.This can reduce network load, because forbidding checking is realized by UE.
For example, back off timer can be initialized in 5007.Back off timer can specify until access is tasted next time
Duration before examination.Back off timer can be limited by bans policy or can not be limited by bans policy.
If judging that access is not prohibited at frame 5002: if using message 5003-5006, to initialize UE130
With the connection between eNB 112.
For example, firstly, UE 130 sends randomly selected random access lead code sequence 5003.For example, can be by preceding
The identifier of the UE 130 of referred to as RA-RNTI is impliedly specified in the timing of the transmission of leading code 5003.
Next, eNB 112 sends physical downlink control channel (PDCCH) traffic order 5004 to UE 130, with
Certain resources are distributed on Radio Link 101.
In addition, eNB 112 sends random access response 5005.The response 5005 indicates to distribute to the interim mark of UE 130
Know, i.e., so-called Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI).In the valid period of C-RNTI, the mark and UE 130 are unique
Ground is associated.
Then, it is based on message 5004 and/or 5005, UE 130 sends wireless heterogeneous networks (RRC) connection request to network
5006.RRC connection request 5006 helps to establish data connection 160 between UE 130 and network 112.
Fig. 3 is instantiated in terms of connecting between UE 130 and network 100.In the example of fig. 3, for certain companies
It meets state 201-203 and defines connection between UE 130 and network 100.For example, under connected state 201, UE 130 and network 100
It is fully disconnected.In this way, network 100 may be unaware that the position of UE 130.It may not transfer uplink data.It may not
Exclusive downlink data can be transferred to UE 130.
In initialization and the connection of network 100, UE 130 is transformed into connected state 203.It, may during connected state 203
Have been set up one or more carryings for data communication.For example, can establish data connection 160.In connected state 203
The address Internet Protocol (IP) can be distributed to UE 130 by period.During connected state 203, it may be possible to network 100 with
Uplink control data is sent on Radio Link 101 between UE 130 and/or downlink controls data.In connected state
During 203, it may be possible to which repeatedly ping UE 130 is to obtain the update about device attribute.
In Fig. 3, another state 202 is instantiated.State 202 is related to inactive state.Sometimes, inactive state 202
Referred to as disconnect state or Idle state.For example, possibly can not between UE 130 and network 100 under inactive state 202
Carry out the communication of payload data.For example, network 100 can not retain the significance bit of UE 130 under inactive state 202
It sets or routing iinformation.For example, UE 130 may be inaccessible under inactive state 202, because serving the net of UE 130
The specific cell of network 100 may be unknown.However, also can will be on some about UE 130 under inactive state 202
Context information is stored into network.This is conducive to that the initialization of connection is made to become simple when switching back into connected state 203.Some
In example, inactive state 202 also can be associated with the update of the periodic Tracking Area of UE 130.For example, in inactive shape
During state 202, UE can the paging of periodically response to network 100 attempt.Sometimes, in 3GPP LTE scene, inactive shape
It is idle that state 202 is referred to as ECM.
In the various examples described in this article, connection can refer to the operation of the UE 130 in connected state 203.At this
In the various examples of described in the text, the initialization of connection can refer to from off-state 201 (for example, in 3GPP LTE frame
EMM is nullified) switching of connected state 203 (for example, the ECM connection in 3GPP LTE frame is connected with RRC) is arrived, and/or from non-
Active state 202 (for example, (the ECM free time is idle with RRC) or (ECM is connected and RRC is inactive) in 3GPP LTE frame) arrives
The switching of connected state 203.In such manner, it is possible to (that is, being initialized according to connected state 203 under off-state 201 and/or Idle state 202
Before connection) execute access barred.This can reduce network load, because network is not involved in access barred.
Fig. 4 is instantiated in terms of connecting between UE 130 and network 100.Fig. 4 instantiate about UE 130 with
The aspect for the carrying 211,212 established between network 100.For example, data connection 160 may be implemented in carrying 211,212.
In the example of fig. 4, the connection between UE 130 and network 100 is realized by default bearing 211.Default bearing and UE
130 IP address is associated.Uplink payload data and/or downlink can be sent via default bearing 211 has
Imitate load data.
In addition, the connection between UE 130 and network 100 includes dedicated bearer 212.Dedicated bearer 212 is held dependent on default
Carry 211.In this way, dedicated bearer is specified by the mark of default bearing 211.For example, specific clothes can be sent via dedicated bearer 212
The uplink payload data and/or downlink payload data of business.It can not be distributed additionally for dedicated bearer 212
IP address.
It, can be for the connection realized by default bearing 211 and/or dedicated bearer 212 according to various examples herein
To realize access barred.Therefore, access barred can be carried out before initialization default bearing 211 and/or dedicated bearer 212.
Fig. 5 is instantiated in terms of network slice.Particularly, Fig. 5 instantiates the side of the slice about core net 113
Face.It in other examples, alternatively or additionally, can be for RAN 114 using slice.
In the example of hgure 5, the network slice 151-153 of core net 113 is defined.Each UE 130 can be with ad hoc networks
It is associated that network is sliced 151-153.For example, each UE 130 can be associated with slice mark.Slice mark can indicate network
Specific one be sliced in 151-153.Then, when initialization and the connection of network 113, based on to and from UE's 130
Slice mark, signaling are routed to corresponding network slice 151-153.
In the various examples described in this article, access barred can be realized based on slice mark.In this way, for accessing
The control parameter forbidden may include slice mark.
Fig. 6 is instantiated in terms of control parameter 5013.In the example of fig. 6, control parameter is (special from network 100
It is to be sent to UE 130 from eNB 112).Control parameter is used for the access for selectively forbidding terminal 130 to network 100.This
Sample, control parameter can form the decision basis for selectively forbidding access.
According to various examples described herein, control parameter can be limited by network in the network 100.In showing for Fig. 6
In example, at frame 5012, control parameter is selected by eNB 112.However, according to various examples, for selecting control parameter 5013
Logic can not also be at eNB 112, but at another network node (for example, MME116 or HSS 115).
In the various examples described in this article, it is contemplated that for selecting the difference of control parameter 5013 at frame 5012
Decision criteria.For example, selecting control parameter based on the device attribute 5011 of UE 130 at frame 5012 according to the realization of Fig. 6
5013.In some instances, device attribute 5011 can be signaled by UE 130, then be received by eNB 112.In other words
It says, UE 130 can report device attribute 5011 to network 100.For example, UE 130 can receive control ginseng from network 100
The feedforward network 100 of number 5013 sends the indicator of indicating equipment attribute.It in other examples, can be from different from UE's 130
Another entity obtains device attribute 5011.For example, can be obtained from network node as such as HSS 115 and/or MME 116
Device attribute 5011.
According to various examples, at frame 5012, different device attributes 5011 can be considered when determining control parameter.Show
Example includes the communication capacity of UE 130；The device type of UE 130；Network associated with UE 130 is sliced 151-153；UE
130 access category；And the operator of subscriber associated with UE 130.
For example, communication capacity can be limited to certain communication protocols (such as 2G, 3G, 4G, upcoming 5G, NB-IOT
Deng) support.For example, communication capacity can limit the frequency band of support.
Therefore, specific implementation is depended on, device attribute 5011 can change.Then, similarly, at frame 5012, it is used for
Determine that the specific selection mechanism of control parameter can correspondingly change.
Once control parameter 5013 has been received in UE 130, then in frame 5014, UE 130 can be according to control parameter
5013 selectively forbid UE 130 to access network (referring to fig. 2) for subsequent connection.
For example, control parameter 5013 may include uniquely/be explicitly assigned to UE 130 UE 130 dynamic marks.
It is thus impossible to which enough fixedly distribute dynamic marks by that will identify to be hard coded into SIM.For example, dynamic marks can be net
What network limited.For example, mark can have certain validity period.After the validity period, the validity of mark can be expired.Example
Such as, validity period can be realized by many purposes, for example, for disposable.For example, validity period can be by until weight
Validity until new distribution is realized.For example, validity period can be realized by timer.It is then possible to again by dynamic marks
Distribute to such as another UE.
Then, by using bans policy appropriate, consider the dynamic marks of UE 130 being previously assigned, it can be selective
Forbid or be not prohibited by access of the UE 130 to network 100 in ground.In one example, the dynamic marks of UE 130 can be C-RNTI
(referring to fig. 2: 5005).Here it is possible to will control during the initialization accordingly connected (for example, during random access procedure)
Parameter 5013 is transmitted to UE 130 from network 100.This makes it possible to be reused as a part of random access with any side
The C-RNTI that formula is sent.
In another example, control parameter 5013 can be sliced the mark of 151-153 by network associated with UE 130
Know to realize.
These technologies make it possible to use for different network operators and/or network slice and/or device type etc.
Different control parameters 5013, and therefore use different access barreds.It is further possible to change control dynamically as needed
Parameter 5013.For example, if it find that some UE 130 is carrying out very frequent access attempts, then it can be true for the UE 130
Determine specific control parameter 5012 and be signaled to the UE 130, to continue to attempt to initialization connection.
In general, these technologies described herein can be applied to the access barred for UE, individually forbid or
It is not prohibited by the access of some UE 130.However, alternately or additionally, these technologies described herein can also be carried out use
In the ACB for forbidding or being not prohibited by a kind of access of UE 130.
Fig. 7 is instantiated in terms of ACB.In detail, Fig. 7 is instantiated in terms of bans policy 300.Fig. 7's
In example, the control parameter 5013 for distributing to different UE 130 is grouped into classification 301-303.For example, classification 301 is cut with network
Piece 151 is associated.In this way, associated with network slice 151 all control parameters 5013 are (for example, correspond to network slice
The unique identification of mark and/or UE 130) it is assigned to classification 301.Similarly, classification 302 corresponds to network slice 152；And
And classification 303 corresponds to network slice 153.
In some instances, the network node for being responsible for distribution control parameter can be based on the relevant device category of given UE 130
Property identify associated with given UE 130 network slice 151-153.Then, UE can choose classification 301-303 appropriate.
Each classification 301-303 can comprise more than a member, that is, may include uniquely being associated with corresponding classification 301-303
Control parameter space.Then, network node can select and the corresponding network of terminal from selected classification 301-303
It is sliced the associated specific control parameter of 151-153.These technologies can also be used for the control of the classification of other types and type
Parameter processed.These technologies facilitate dynamic ACB.
In the example in figure 7, bans policy 300 is specified allows to have and classification 301,302 associated control parameters
The access of 5013 all UE.Bans policy 300 is also specified to forbid the UE with control parameter 5013 associated with classification 303
130 are linked into network 100 (being indicated by the dotted line filling region in Fig. 7).One example, which can be, forbids belonging to the confession of some electric power
The access of all intelligent meters (associated with network slice 153) of quotient is answered, while allowing to belong to the institute of some gas supplier
There is access of the intelligent meter (it is associated to be sliced 151,152 with network) to network.
In the scene of Fig. 7, the bans policy 300 for being transmitted to UE 130, which may not explicitly indicated, to be prohibited to access net
All control parameters 5013 of network 100.If control parameter is uniquely attributed to UE 130, this may be particularly useful, because
If not being uniquely attributed to UE 130 for control parameter, it may be necessary to send UE for a control parameter long list
130.On the contrary, bans policy 300 can indicate all control parameters 5013 forbidden in a manner of parametrization, this makes UE
130 can conclude that whether its unique and individual control parameter 5013 is actually prohibited to access.This may include bans policy
300 and/or control parameter 5013 some processing.In other words, bans policy can be indicated for forbidding being linked into network 100
Control parameter 5013 classification.It is this parametrization instruction another example is use modular function.For example, UE 130 can pass through
Mould (10) are executed to the unique identifier (such as C-RNTI) of storage to calculate the dynamic access classification indicated by bans policy.Make
Signaling overheads can be reduced with compression/parameterized form bans policy.
In general, in the various examples described in this article, the access of terminal can be forbidden based on multiple control parameters.This
Multilayer can be referred to as to forbid, because determining to have to check for multiple standards when forbidding or being not prohibited by.For example, can be based on
Access barred is realized by the combination of the temporary identifier of network distribution.For example, some slice 151-153 can be defined as include
It may forbidden UE.It is then possible to forbid being connected to the particular slice and all UE with C-RNTI mould (10)=0.
In general, bans policy 300 specifies whether some UE 130 is prohibited to access network 100 in which can determine.Optionally
Or additionally, probability can also be used.For example, different access categories can with become some forbidden statistical likelihood phase
Association.This scene is instantiated in fig. 8.
Fig. 8 is instantiated in terms of bans policy 300.The scene of Fig. 8 generally corresponds to the scene of Fig. 7.However, instead of
Deterministically forbid certain classification 301-303, according to the example of Fig. 8, bans policy 300 may include forbidding having falling into accordingly
A possibility that 130 UE of related control data in classification 301-303.
For example, classification 301 is 20% associated with probability is prohibited.Namely based on some random contribution, there is classification 301
The UE 130 of middle control parameter 5013 is prohibited or is not prohibited by access network 100.Differently, for being controlled in classification 302
The UE of parameter 5013 processed, forbidden possibility are equal to 0%.For the UE 130 with control parameter 5013 in classification 303, quilt
A possibility that forbidding is equal to 100%.
In the various examples described in this article, control signaling can be used to send bans policy 300.Control signaling can
To be the 1st layer, the 2nd layer or the 3rd layer of signaling in osi layer model.It is, for example, possible to use forbid bitmap to send bans policy
300.Forbid bitmap that can specify for the classification of each control data and/or control data and individually forbids information.
Fig. 9 is instantiated in terms of bans policy 300.Particularly, Fig. 9 is instantiated about Limited service quality (QoS)
The aspect of the bans policy 300 of threshold value 355 (horizontal dotted line in Fig. 9).
Fig. 9, which is also illustrated, seeks initialization Service Quality associated with the service of the connection of network 100 with corresponding UE 130
Amount 351.For example, can in the application layer of osi layer model Limited service.For example, service can be with certain payload datas
It is associated.For example, the service can be related to music stream, audio call, internet, packet data network connection etc..
In addition, what is illustrated in Fig. 9 is QoS benchmark 352.As from Fig. 9 it will be apparent that being limited relative to QoS benchmark 352
The QoS 351 of service keeps below QoS threshold 355.Such scene can correspond to that UE130 is forbidden to access network 100.It is different
Ground, if being more than the QoS threshold 355 limited by bans policy 300 relative to the QoS 351 that QoS benchmark 352 limits, this can
It can relate to be not prohibited by access network 100.
In some instances, QoS benchmark 352 may be derived from the control parameter 5013.For example, based on unique control ginseng
Number 5013 can determine different QoS benchmark 352 for different UE 130.For example, can be directed to associated with UE 130
Heterogeneous networks slice 151-153 determines different QoS benchmark 352.
In one example, be able to use C-RNTI as in conjunction with QoS (for example, being expressed as 3GPP LTE QoS classification
Identifier (QCI)) UE 130 unique identification, to realize priority difference between external network, but still in local network
QoS is used in network.Here, C-RNTI can limit QoS benchmark 352.For example, the C- combined with the QCI corresponding to QoS 351
RNTI mould (10)+1=1 can provide the number lower than C-RNTI mould (the 10)+1=2 combined with identical QCI value.If forbidding plan
Slightly 300 QoS threshold 355 is suitably specified, then this makes it possible to dynamically change heterogeneous networks slice by C-RNTI
Priority between 151-153；In each classification 301-303 associated with heterogeneous networks slice 151-153, it can be based on
QoS 351 carries out priority ranking to business.Therefore, it can be distributed for access barred between network in priority and network
Priority.Such example is based on the C-RNTI of the unique identification of UE 130 not only to realize, but also can be easy
Ground is applied to the variety classes of UE 130 and the unique identification of type.
In other examples, control data 5013 can limit threshold value 355, and bans policy can limit QoS benchmark
352.Under any circumstance, bans policy can specify qos requirement.
Figure 10 is signaling diagram.Figure 10 is instantiated in terms of transmission bans policy 300.In the example in Figure 10, UE
130 to network 100, particularly sends request 5021 to eNB 112.In response to receiving the request, eNB 112, which sends instruction, to be prohibited
The only response 5022 of strategy 300.In this way, UE 130 can be configured as requesting bans policy 300 from network 100.
If such compared with bans policy 300 is broadcasted repeatedly the scene of (for example, a part as SIB)
Scene can contribute to reduce the control overhead on Radio Link 101.Therefore complicated in bans policy 300 simultaneously includes big data word
In the case where section, this may be especially true.In this case, bans policy 300 is sent directly to UE as needed
130 can be more efficient.
Next, UE 130 checks if it should forbid accessing network 100 at frame 5023.For example, at frame 5023,
UE 130 can check the update of bans policy 300.
In general, in the various examples described in this article, can divide by updating bans policy 300 and/or by updating
The control parameter 5013 of dispensing particular UE 130 realizes the dynamic attribute of access barred.For example, being responsible for distribution control parameter
Network node can monitor the business load of multiple networks.Then, network node can be based on the monitoring come by new control
Parameter is reassigned to terminal.For example, being capable of forming more by one or more control parameters for redistributing various terminals
Stringent or loose forbids.General, it may be desirable to control parameter 5013 be updated, for example, distributing to the interim mark of particular UE 130
Know, rather than updates bans policy 300.This can aid in the expense for reducing the control signaling on Radio Link 101, because logical
Normal bans policy 300 can have significant size.It is thus possible to more dedicated access barred function enough be realized, because of network
100 for example dynamically can distribute control parameter according to the device attribute of particular UE 130 and/or newest network slice
Different value.
Figure 11 is instantiated in terms of UE 130.UE includes processor 1301.UE further includes memory 1302.Memory
1302 can be nonvolatile memory.Memory 1302 can store program code.Program code can be by processor 1301
It executes.Executing program code can make processor 1301 execute various technologies described herein, be related to: as such as ACB
Access barred, to network sending device attribute, receive and store control as the mark that such as dynamic marks or network are sliced
Parameter etc..
Figure 12 is the flow chart according to each exemplary method.For example, can be by UE's 130 according to the method for Figure 12
Device 1301 is managed to execute.
Firstly, receiving control parameter in frame 6001.Control parameter is received in the first connection.For example, can be first
The received during initialization control parameter of connection.Alternately or in addition, control can be received after being successfully established the first connection
Parameter processed.
Control parameter can indicate the unique identification of UE.For example, unique identification can be it is interim.Control parameter can also be with
It is not uniquely attributed to UE.For example, control parameter can indicate network slice associated with UE.Because network slice can be with
The multiple UE of trustship, so in such a case it is not necessary to control parameter is assigned uniquely to UE.
It is then possible to storing control parameter, to use control parameter to carry out access barred later.For example, in frame 6001
It between frame 6002, may pass the plenty of time, for example, several minutes, a few hours or a couple of days.For example, in frame 6001 and frame
Between 6002, the various changes of the connected state of UE can occur, for example, being transformed into off-state and/or Idle state from connected state.
Particularly, in frame 6002, it is based on control parameter, selectively forbids accessing network for the second connection.Second
Connection can be different from the first connection.For example, can second connection initialization during or second connection initialization it
It is preceding selectively to forbid accessing network.For example, step 6002 can be executed before being switched to connected state from Idle state.For example,
Can establish such as default bearing or dedicated bearer as carry before or period execute step 6002.
Forbid access that can be related to preventing from sending access attempts or connection request to network in frame 6002.In frame 6002
The connection for forbidding access that can be related to abandoning with network is attempted.Particularly, the logic of frame 6002 can be in UE, so as to subtract
Shaoshi is added in the load on network (at two aspect of signaling and processing).
Figure 13 is instantiated in terms of eNB 112.ENB 112 includes processor 1121 and memory 1122.For example, depositing
Reservoir 1122 can be nonvolatile memory.Memory 1122 can store program code.Program code can be by processor
1121 execute.Processor 1121 can be made to execute various technologies described herein for example, executing program code.These technologies can
To comprise determining that the control parameter for UE；The control parameter for UE is determined based on the device attribute of UE；From UE and/or
Another network node receiving device attribute；Monitoring business loads and configures access barred etc. based on the monitoring.
About Figure 13, eNB 112 has been directed to it and has explained various aspects.However, these technologies can also be applied to network
Other network nodes as 100 such as gateway 117,118 and/or control node 115,116,119.
Figure 14 is the flow chart according to various exemplary methods.It can be by the processor of eNB 112 according to the method for Figure 14
1121 execute.Similarly, according to the method for Figure 14 another net as such as gateway node or control node of network
Network node executes.
In frame 6011, UE is sent by control parameter.UE is sent by control parameter in the first connection.Control parameter
Access barred of the enabling/promotion UE in subsequent second connection.
For example, this method can also include determining control parameter before sending control parameter.For example, if will access
Forbid realizing as ACB, then can select the classification of control parameter based on device attribute.For example, device attribute can be at certain
It is grouped in a little classifications.Then, according to the grouping, particular category can be identified.Each classification can have associated therewith
The space of the control parameter of connection；It is then possible to select specific control parameter from the classification of control parameter.For example, such as
Fruit device attribute indicates some network slice associated with UE, then can select control parameter associated with network slice
Classification.For example, some network slice can have a certain amount of control parameter, each control parameter uniquely identifies available
It is associated with UE.It is then possible to select specific control parameter from those of being limited by the classification of control parameter in candidate control parameter.
In some instances, control parameter can be sent when dynamically updating access barred attribute.For example, can monitor
The business load of multiple network slices.Then, if business load be more than some threshold value, can distribute new control parameter with
Just tightened up access barred strategy is realized.It then, can be for example in push communication using updated control parameter as frame
6011 a part is sent to UE.Alternately or in addition, additionally it is possible to which bans policy is updated based on the monitoring to business load.
Then, UE for example can be sent to using updated bans policy as a part of frame 6011 in push communication.
In other examples, this method can also include sending bans policy to UE.Which control is bans policy can specify
Parameter processed is limited by access barred.For example, the business load of multiple network slices can be monitored again.It is then possible to based on pair
The classification of business load monitored to select control parameter.For example, can choose and to be limited by tightened up access barred
Some network is sliced the classification of associated control parameter.Then, once having identified the classification of control parameter, it will be able to
UE sends updated bans policy, and bans policy instruction is for forbidding accessing the selected control parameter classification of network.
In a word, it has been described that can be realized the above-mentioned technology that dynamic access is forbidden.Compared with the reference of ACB is realized, this
A little technologies provide certain advantages.For example, the RAN realized according to reference usually only has, there are two types of priorization/control business hands
Section.A kind of scene is using traffic filter information as such as QCI.Another scene is in congestion/traffic overload feelings
Forbid user under condition.It has been found that certain types of service in network are usually arranged (for example, audio call or internet industry in QCI value
Business) priority.However, this QCI will not provide between any network since network slice can be considered as dedicated network
Priority.ACB is the means for reducing the business in RAN.However, the reference of ACB, which is realized, uses blind statistic law.Therefore, according to ginseng
Realization is examined, priority between network can not be provided.In addition, in shared RAN (that is, being used by the operator that multiple networks are sliced
RAN) in, RAN will be each operator realize have equal priority ACB.
This is based on the discovery that be based in accumulation (accruing) subscriber identity module according to the ACB that reference is realized
It is supplied to the static state and predefined number of user.For example, being realized according to reference, access category 0-9 uniformly divides between devices
Cloth.
Differently, according to various examples described herein, interim control parameter can be distributed into UE by network.Control
Parameter can be used for realizing access barred.It, can according to the restriction of control parameter and/or according to the restriction of corresponding bans policy
Realize the specific access barred of equipment and/or ACB.
Although being directed to certain preferred embodiments has shown and described the present invention, is reading and understanding specification
Later, those skilled in the art will expect equivalent and modification.The present invention includes all these equivalents and modification, and only by
